Abstract: Objective: To investigate the chemical composition of the fermentation broth of the traditional medicinal fungus
Fomitiporia punctata. Methods: The ethyl acetate extract of the fermentation broth of F. punctata was isolated and purified using
silica gel column chromatography, gel chromatography, liquid chromatography, and preparative HPLC. The structures of the isolated
compounds were identified by nuclear magnetic resonance spectroscopy and mass spectra. Results: Six compounds were isolated from
the fermentation broth of F. punctata, namely punctatin A (1), 3β -hydroxycinnamolide (2), Cyclo(L-Pro-L-Tyr) (3), Cyclo-4-
hydroxy-(L-Pro-L-Leu) (4), 5-hydroxymethyl furfural (5) and p-hydroxybenzoic acid (6). Conclusion: Compound 1 is a new
compound, and compounds 1-6 are isolated from F. punctata for the first time.

Key words: Fomitiporia punctata, chemical composition, benzene ring derivative, isolation and identification
